Specification of Letters Patent.

Patented Dec. 15, 1908.

Application filed November 21, 1907. Serial No. 403,217.

To all whom it may concern:

Be it known that I, ANDREW CHRISTIAN- soN, a resident of Butler, in thecounty of Butler and State of Pennsylvania, have i11- vented a new anduseful Improvement in Journal-Box Lids; and I do hereby declare thefollowing to be a full, clear, and exact description thereof.

This invention relates to journal boxes and lids therefor and moreespecially to those adapted for motor trucks.

The object of the invention is to provide a journal box lid having noprojecting portions liable to strike against obstructions and bedamaged, and which is so constructed that it can be readily removed whendesired and securely locked in place in use.

The invention comprises the construction and arrangement hereinafterdescribed and claimed.

In the accompanying drawing Figure 1 is a vertical section through theend of a journal box showing the lid applied thereto; Fig. 2 is asimilar view showing the parts with the lid unlocked; Fig. 3 is ahorizontal section on the line 3-3, Fig. 2; Fig. #l is a similar sectionon the line 1l:, Fig. 1,; Fig. 5 is a vertical section on the line 5-5,Fig. 2; and Fig. 6 is a detail view of the locking lever.

The journal box is shown at 1 having an outer open end or mouth and maybe of any desired pattern. The top wall 2 is provided with an upwardlyprojecting flange 3 and the bottom wall 1 is provided on its outer facewith a recess or depression 5 and the edge of said lower wall isprovided with a notch 6 and with downwardly projecting on either side ofsaid notch. The lid 8 may be either a casting or of pressed metal, beingshown as a casting, and is provided with side flanges 9 fitting snuglyoutside of the side walls 10 of the axle box, and at its top has adownwardly projecting flange 11 adapted to hook over the upwardly projecting flange 8 on the top wall of the box. The lid is providedcentrally with an outwardly bulging portion 12 providing a chamber 13 onthe inner side of the lid. At the bottom of said chamber is a pocket 15having a hole 16 through its bottom. Seated in the pocket 15 is a spiralspring 17 which surrounds a rod or boltlS having at its upper end a nut19 bearing on the upper end of the spring. Said rod or bolt extendsdownwardly through the hole 16 in the bottom of the pocket 15 and whenthe lid is locked projects downwardly through the notch 6 in the bottomwall of the box. At its lower end it has an eye 19 for receiving thepivot pin 20 of a locking lever 21. This lever has cam or toe pieces 22arranged to engage the downwardly projecting shoulders T on the bottomof the box, and also has a projecting face 23 arranged to engage thelower-edge of the lid and lift the same. The lever is provided with ahole 2-l for the insertion of a bar or the like to operate the lever ifnecessary.

Fig. 1 shows the lid in locked position with its top flange l1 lyingbehind the top flange 3 of the box and with the locking lever 21 pushedinwardly and lying in the recess 5 in the bottom face of the box. Inthis position the cam members 22 of the lever are thrust against theshoulders 7 on the bottom. walls of the box and securely hold the lid inlocked position. To unlock the lid the lever 21 is pulled downwardly andoutwardly to the position shown in Fig. 2 thereby releasing the lowerend of the rod 18 and permitting the lower edge of the box to be swungoutwardly, the projection 23 engaging the lower edge of the lid andlifting the same. IV hen the lid entirely clears the box it can belifted ofl. The mouth of the box is curved backwardly at the top and thelid is correspondingly curved. When the lever 21 is in looking positionthe spring 17 is compressed and exerts a downward pull on the lid. Thisnot only serves to hold the top flange of the lid behind the top flangeof the box, but also by reason of the curved contour of the lid andmouth of the box causes the lid to 9 be firmly pressed against the edgesof the box mouth and form a tight closure. The box is shown providedwith grooves 25 for receiving the usual gib or forked plate used forholding the axle against endwise movement.

The arrangement shown provides an axle box lid having practically asmooth exterior so that when used for motor car purposes, such as incities, there are no projecting parts to hit against trucks or otherobstructions. The lid fits very tightly over the' mouth of the box,making the latter practically dust proof. The locking device holds thelid securely in position so as to prevent the same falling off inservice but at the same time is so constructed that the lid can bereadily removed whenever desired.

hat I claim is:

1. The combination of a ournal box having an outwardly projecting flangeat its top, a lid provided with an inwardly projecting flange at itstop' arranged to engage behind said flange on the box, a lever ar-"ranged to lock the lower edge of the lid to the box, and a yieldingmounting for said lever.

2. The combination of a journal box having an outwardly projectingflange at its top, a lid provided with an inwardly projecting flange atits top arranged to engage behind said flange on the box, a cam memberarranged to lock the lower edge of the lid to the box, and a yieldingmounting for said cam member.

3. The combination of a journal box having an outwardly projectingflange at its top, a lid provided with an inwardly projecting flangearranged to engage behind the top flange of the box, a cam membercarried by the lid and arranged to engage the box, and a springconnection between said cam member and the lid.

t. The combination of a journal box provided on its bottom with ashoulder or shoulders, a lid fitting over the mouth of the box, ayielding member carried by said lid, and a lever pivoted to saidyielding member and arranged to engage the shoulder on the box.

Ihe combination of a journal box having an outwardly projecting flangeat its top, a lid provided with an inwardly projecting flange at itstoparranged to engage behind said flange on the box, and a lever forlocking the lower edge of the lid to the box, said lever having aprojection arranged to engage the lower edge of the lid and lift thesame.

6. The combination of an axle box having its lower wall notched andprovided with downwardly projecting shoulders, a lid fitting over themouth of the box, a spring pressed rod carried by the lid, and a leverpivoted to said rod and provided with cam projections for engaging theshoulders on the box.

7 The combination of an axle box having its lower wall notched andprovided with downwardly projecting shoulders, a lid fitting over themouth of the box, a spring pressed rod carried by the lid, and a leverpivoted to said rod and provided with cam projections for engaging theshoulders on the box and with a cam arranged to engage the lower edge ofthe lid and lift the same.

8. The combination of an axle box provided on its top wall. with anupwardly projecting flange and having its bottom wall notched at theforward edge and provided on the lower face with a recess and with adownwardly projecting shoulder at the edge, a lid having at its upperedge an inwardly projecting flange to fit over the flange on the top ofthe box, a spring pressed bolt or rod carried by the lid and arranged toproject through the notch in the bottom wall of the box, and a leverpivoted to said bolt or rod and provided with a cam member for engagingthe shoulders on the bottom of the box and arranged when in lockingposition to lie in the recess in the bottom wall of the box.

In testimony whereof, I the said ANDREW CHRTSTIANSON have hereunto setmy hand.
